[PATCH v2] pvcalls-front improvements

[Stefano Stabellini]

Hi all,

this small series introduces a per socket refcount to increase the
efficiency on socket release operations, and makes releasing passive
sockets safe.

Cheers,

Stefano


Changes in v2:
- add acked-by
- fix check in pvcalls_enter_soc
- fix code style
- nicer checks in pvcalls_front_release


Stefano Stabellini (2):
      pvcalls-front: introduce a per sock_mapping refcount
      pvcalls-front: wait for other operations to return when release passive sockets
